Abstract: An apparatus for the prevention of overflowing water in a syphonic flush cistern comprises a closed pipe (22) attached to the syphon in communication therewith above the normal water level (16) of the cistern, the pipe having an air inlet (28) at or near the top thereof normally closed with a float (30) which is displaced under overflowing conditions. The pipe may be an overflow pipe (22) attached to the "down" leg (18) of the syphon and extend downwardly to a depth at least level with the air inlet of the syphon system. The pipe may be formed integrally with the down leg of the syphon or may be fitted to a standard commercial syphon ('retro-fitted'). The float is preferably arranged with a flotation cell on either side of the overflow or closed pipe so as to stably remain in place during normal usage of the cistern. In addition, the float body preferably has a weight bias so that it will tend to topple over when released from the sealing position thereby ensuring as far as possible that it cannot reseal after activation. Once the device of the invention has been activated, the WC will no longer flush and so the user has a warning that something is amiss and on inspection will note that the float has been displaced. The fault may then be corrected and the float manually replaced, after which the device of the invention is ready to be tripped should there be another fault. Any continuing overflow of water is visible in the toilet pan.

Title: Photonic quantum information system using unpolarised light
Inventor: YUAN ZHILIANG
IPC: H04L9/08
Filed: 2003-03-06
Abstract: A photonic quantum information system includes a photon emitter comprising a photon generator which generates photons having first or second orthogonal polarisation states. Time delay means introducing delays between photons having the two different polarisation states, may comprise a polarising beamsplitter directing photons having different polarisation states along different length optical paths, or a single path polarisation maintaining fibre. For quantum cryptography, the photons may be encoded for example by varying the relative phase or rotating the polarisation. To encode the phase of a photon, an interferometer has an entrance coupler connected to a long arm and a short arm joined at their other ends by an exit coupler. One of the arms introduces phase modulation. Photons generated with different polarisation states can be encoded with different signals because they are temporally separated within the encoding equipment, allowing all photons generated with random polarisation states to be utilized, if for example they are passed through a polarising beamsplitter to generate the two orthogonal polarisation states. A photon receiver comprises a detector and gating means. Other aspects of the invention include a photon emitter and a polarisation distinguisher.

Title: Separation of carrier film from electrophoretic gel in an electrophoresis blot process
Inventor: DAVIES ANTHONY MITCHELL
IPC: G01N27/447
Filed: 2003-09-12
Abstract: A cast gel slab 2 for electrophoresis (for example a western blot process) comprises channels 8 cast into the slab. In use, after a transfer process has been completed between the gel slab 2 and a carrier film 5, fluid (preferably a buffer fluid) may be pumped at high pressure through the channels causing the film and gel to separate. As separation continues the fluid flows into the spaces created by the separation and further perpetuates the separation. In a second embodiment a fluid of high molecular weight (for example sorbitol) is sealed into the channels. Fluid will migrate via osmosis out of the gel into the high molecular weight fluid and thus cause the pressure to rise. Separation continues as in the first embodiment. In a third embodiment the pressured embodiments wets the carrier film to a greater extent than the gel and thus seeps more readily between the carrier film and the gel easing the separation. The carrier film may be nitrocellulose and the fluid a buffer solution, or the film may be PVDF and the fluid a methanol/acetone mix.
